A-level Studies in Oxford UK

I am Siya Kali, a 22 year old South African student looking to study Engineering at Cambridge University in the UK. In order to study at a UK university, I need to study A-levels. I have been studying the UK syllabus from home for a few years, and based on the strength of my current grades - an A for Physics and an A* for Computer Science, my grades for Mathematics and Chemistry will be released this August - and various online interviews, I have secured a provisional place to study A-levels at an A-level college in Oxford - Greene's Tutorial College. Based again on the quality of my grades and interviews, the college offered me a 70% tuition scholarship, and I am creating this page to fund both the outstanding 30% tuition fees and the accommodation I need once in the UK. These funds would cover the first year of my 2 year A-level course, and any assistance would be deeply appreciated.
